INTRODUCTION
GF312B portable three phase watt meter calibrator with printer is used to calibrate three phase, single phase, active and reactive watt meters. And it also can be used as voltage, current and power meter to measure AC parameters of three phase power line.It can measure wave distortion factor and 2nd to 63th harmonic wave.
